srLrr-RIM einfsn'rern'nn- To all whom #mag/.concern l vBe it known thatI, EDWARD A. BANSCH- BAoH,`a -citizen of the'United States, resid ing atChicago, in the countyof Cook and Sta-te of'lllinois, have v inventedcertain new and useful Improvements inVSplit-Rim Air- Retainers, ofwhich the following is Ia speci-A lication.

Ilhis invention relates to a device for hold-V ing a split rim and atire therefor in in-` Hated .condition so that the 'ri-m and tire can becarried and substituted for a demountable rim and tire'of the same, or adifferent kind, as commonly used with automobiles.

' rlhe object of the invention is to make:

practical the use of a rim split longitudinally so that an inflatabletire maybe used therewith, thereby preventing the diiiiculty .nowexperienced 1n applying a tire to a'rim and removinga a tire from a rim,and in further overcoming the diiiculty which occurs when a tire-freezes`toa rim.

The invention consists in the novelconand` arrangement of struction,combination the parts.

ln the accompanying drawing- Figure l is aside elevation of a rim andtire holder constructed in accordance with the principles of thisinvention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. l. v l

Fig. 3 is a longitudinal sectional' view of y one of the hinged joints;and

Figs. 4, 5 and 6 are modified constructions which may be usedat theintersection of the rimparts.

lt has been found that after an lautomobile rim and its tire have beenin service for sometime, the tire invariably sticks or freezes to therim and it is very di'cult to remove the tire for substituting a newone, or for having access .to the inner'tube to repair or replace it.Furthermore, it is. desirable to carry eXtra tires and rims of theldemountable type with the .tires inflated so that a tire which hasfailed can,`

be removed and Va properly inated one substituted. rlhe inlation of atire on a longitudinally split rim tends to force the rim sections aparteven though the parte f of the casing itself do adhere firmly to the rimparts and, therefore, some'means must be provided for holding the rimand the tire in an inflated condition. The present invention complieswith all of the above rel `sections '1, each of which `quirements andpermits thel application of suche-a rim Vand tire to the wheel of anautomobile where the rim is first attached toy the automobile wheel, andthen the holder `of the present inventionis removed.

lhe easing'is split longitudinally at or adjacent the center of the rimformed by the two' rim sectionsv l so that even if both of the rimsections adhere tightly to thecorresponding parts of the casing, the rimsections can be separated when the rim and tire are removed from thewheel by prying the sections apart, or by forcing them apart due to thepressure of the tube 4, so that the tube 4 may be removedand a new tubeinserted, when desired.

lt is obvious that some means must be provided forholding the rimsections together when the tire is inflated and is not applied tothewheel "of an automdbile in order that the complete tire and rim may` beready for 'use and may be substituted Afor a punctured tire.` Ail numberof clamps 51are therefore provided which are gener# iciently large topass'loosely over the tire from theoutside thereof. The ends o fgithe vy clamps are formed with threaded extremie ties 6 through which 7 areadjustable, `each carrying a loose bearing member 8 I Specicaton ofLetters Patent.

- ally U-shaped in` constructionandv aresuff 'f which `is pressedagainst the flange 2 of the rim section so that when the clamp issecured in place,- the rim sect' pressed kllfirmlytogether. thereby tirein its inated condition,

Any suitable means may be used for spacing the clamps apart.; a band 'ofmetal may be used, and the number of clamps for' each rim is preferably"the same as the number of clamps onthe wheel lons will be" holding the.

fabric cover, o r a of the automobile for clamping the de- A mountablerimand tire in position. The :i

spacing'means shown in Fig.' lv .comprises a plurality of sections 9 ofthin metal, or the like, connected by outer periphery threaded member 11and a winged nut l2 is provided for holdingthehinged sections 9 hingesl0 near the so that the sections may 'be'swung outwardly to clear thetire in reautomobile. In Fig. 2 the numeral lll'des-v ignates .the rimor folly of an automobile wheel which has an inclined upperface in usualpractice so that the rim parts 1 will slide thereon from the outer side'of the wheel and may be held firmly in place on the rim by the clampingbolts, not shown, in connection therewith. i

As shown in Fig. 2, one of the rim sections, or both of them if desired,is p rovided with a projection 15 which engages beneath the other rimpart holding the two rim parts in alinement so that they may be pressedtogether more readily. Instead of the construction shown by Fig, 2, apin and reccss/ connection as shown by Fig. 4, an angular edgeconstruction as shown by Fig. 5, or a shouldered edge construction asshown by Fig. 6 may be employed. Itis obvious' that any of these formswill serve to guide and retain the rim parts in proper position withrespect to each other. l l

lIn using this rim and tire holder the clamps are applied to anassembled tire and a split rim before the tire is inflated, and

after the tire is inflated it may be carried as an eXtra tire anddemountable rim of the well-known type. l'When it becomes necessary tosubstitute this for another de= mountable rim and tire, the wholestructure is pressed over the felly of the wheel and the split rim isclamped in place from the sides, holding it rigidly in place on thewheel, the clamps are then loosened by unscrewing the bolts 7 and theholder. as a whole is removed after unscrewing the attaching nut 12 sothat the hinged sections 9 can be' removed from the tire.
